Question

Rhesus monkeys and gorillas have stereoscopic vision, which allows them to better visually gauge distances while hunting and moving through tree canopies. If stereoscopic vision evolved only once on this tree, and was never subsequently lost, which other primate species on the evolutionary tree possess stereoscopic vision as well

Answer 1

The complete question is attached as an image with the evolutionary tree:

Answer:

The correct answer is option D. Gibbon, orangutan, common Chimpanzee, bonobo, And Human.

Explanation:

The arboreal life of primates is possible by adapting from the tree-dwellers. Therefore the tree-dwellers are ancestors of all primates. The adaptation primates developed and exhibits are such as thumb for grasping, separated big toes, rotating shoulder joint and stereoscopic vision.

Stereoscopic vision is to provides better vision to have a better view and sharp vision to see an object from distance and moving through trees. It is present in almost all including Gibbon, orangutan, common Chimpanzee, bonobo, And Human.
